To all lwhom it may concern.'

Be it known that I, ALBERT H. DE VoE, a citizen of the United States,residing at lfVestfield, in the county of Union and State of' NewJersey, have invented certain new and useful Improvements inOverseaming-.Stitch-Forming Mechanisms, of which the following is. a specificatlon,reference being,

had therein tothe accompanying drawings. This invention relates to animprovement in loverseaming stitch-forming mechanlsm,

and it is designed' more particularly for stitching togetherv andserging the 'superposed marginal portionsof the uppers and soles ofJapanese footwear known as tabis,

The invention has for its object to provide'a simple and effectivemechanism of this class which shall be strong and durable and inwhichthe needle-jogging meansis so arranged as to prevent obstructingthe oper-` ators view of the work. u l

It has for its furtherobject to 'provide mechanism for'v producingastrong Seam for uniting' the soles and' uppers of the tabis and foreffectively `confining their raw edges to prevent raveling.

As preferably constructed. the machine is provided with a rectilinearlyreciprocating sectional tubular needle-bar carrying a fixed and alaterally movable needle and having a fixed bearing embraced bythespaced mem.- bers of a yoked rocking frame journaled upon saidneedle-bar and connected withl suitable means for imparting rockingmovements thereto. Journaled lwithin the' needle-ca-rrying section ofthe 'needle-bar and having a bearing in the other-section thereof `is acrank-'rod having at its lower' end a crank operatively connected withthe carrier for the laterally movable needle and at its upper end alateral arm fixed thereon intermediate the adjacent ends of theneedle-bar sections and having a pivotal and sliding connection' withsaid rocking frame,V wherebv the jogging movementsl are imparted to thelaterally'movable needle by a connection with the rocking frame passingthrough the needle-bar so as to reduce to the smallest bulk possibletheparts carried by the needlebar nearest thework. The joggingneedlecarrier is'preferablyin the form of a slideblock mounted in atransverse slideway of the j needle-bar and having a lateral arm formedwith a .stud embraced by the eyed endof a slide-pin entering a radialsocket in the crank at the lower end of lsaid crank-rod.

the needle-bar-actuating shaft, thereby imparting two rotations of theloop-takers to each reciprocation of their respective needles. `One oftheloop-taker Shafts is mount-- ed in a fixed bearing bracket and theother upon a jogging `frame having a fulcrum vtransverse to saidvloop-taker shafts and tov the intermediate shaft and`v provided with alateral arm connect-ed vby a` pivotal pin with a block apertured to.embrace an actuating eccentric loosely mount-ed upon said intermediateshaft and rotating at one-.half the speed of the needle-driving shaft.

The jogging frame carries a holding arm adapted to` engage a portionofithe threadcase of the jogging loop-taker to restrain it from rotationtherewith and in this arm is secured a thread-controlling finger adaptedto engage'the lower thread of the jogging lloop-takerand to take up andgiveout slackrespectively in' the in-throw and out-'throw of theloop-taker relatively to the fixed or Arectilinearly vreciprocatingneedle. This lfin"- ger also serves to control the lead of theneedle-thread `between the loop-taker andthe fabric as it is drawn up bythe take-up.

The frame of the machine is constructed prising the hollow?, standard 2and .the overhanging tubular member 3 terminating in the hollow head 4vformed at the top with [the boss 5 aiording the upper needlefbarbearing and 'at the bottom with the member 6 having the bushing 7afordingthe lower needle-bar bearing, in which-#bearings arejournaledthe spaced upper and lower secadjacent end portions of theneedle-bar Sections'are rigidly coupled'together by means 'of a splitvcollar 10 clamped thereon by screws 11 and formed in oneside'intermediate the ends'with a deep notch 12 extending beyond theopposite side of the needle-bar,

i and carrying atthe opposite sidea lateral stud 13 embraced'by the aertured lower. end of the link 14 connecte -with the usual crank-pin 15upon 'the take-up cam-cylinder 16 fixed upon the forward endv of therotary main-shaft 17 The lcylinderl is provided with the cam-groove 16entered by the roller-I stud 18uponthe lateral arm 18 of the takeup arm19 mounted upon the fixed fulcrumstud 20.

AAs shown herein, the main-shaft 17 has ixed'thereon the switch-cam`21having the grooves 22 entered by the follower 23 pivotally mounted bymeans ofthe pin 24y upon the lower arm 25 `of a rock-lever fulcrumed at26 upon the arm 3 and having an upper arm 27 upon'which'is adjustablysecured.`the shouldered stud 28 passing throughv the yslot 27 .of saidarm and provided with the clampenut 29. The stud 28, which in prac-vtice is formed with a spherical extremity is embraced byA one end 'ofalink 30 whose apertured opposite end embraces the ball screw-stud 3ltapped into the laterally pro- A4jectingboss 32 of the rocking frame 33yoked to form the spaced members 34 and 35 embracing the' bearing boss 5and apertured to vtit the needle-bar section `8 upon which said yoke visjournaled to swing, The'frame 33 is bored out to form a guideyway 36 toreceivethe pin 37 which is secured by .means of setscre"ws 38 withinthegapertured boss 39 o f an arm 40 having a split hub 41adjustablyclamped by means of the screw 42,1 1pon' the`upper portion ofthe oscillating-'crank-,rod .43 which is ournaled within the bore ofthelower needle-bar section-9 and \vhose upper`end .portion is received ina bearing therefor alforded by the upper. needle-bar section 8, asrepresented in Fig.7, the arm 40 entering the slot 12 of the split,coupling collar 10 between the adjacent ends of the needle-barsections.

The rod 43' has'ixed upon its lowerend the 'crank`44 formed with aradial socket 44 .entered by the sliding-'pin 45 having the transverseboss 46 apertured to form the eye 47 embracinga stud 48 carried by therearwardly extending arm 49 of the needlecarrying slide-block ISO-whichis provided with the.depending-portionl having the usual .needle-Socket52 in which is secured by Ameans of the setscrew 53 the' laterallyjogging needle 54. The slide-block 50 is fitteclwithin a transverseslideway 55 in the liXed needle-,carrier 56 formed with the lateral slot57 for the arm 49 of the slideblock 50 andbaving the depending part 58Iwith needle-socket 59 in which issecured hy -means of the set-screw 60the fixed needle 61.

As Willbe-seenv .byreference more particularly to Figs. 3, 11v and 13,the needle 5 4 performs its lateral jogging movements in a planerearward of the fixed needle 61. To facilitate the assembling oftheparts, the arm 49 is provided with a shank portion entering a'slot inthe block 5() in which it is ing with that of the needle-bar, while thejogging needle 54 has in addition to its endwise movement a lateraljogging movement communicated thereto through its connection with theoscillating rod 43 housed within the hollow needle-bar'and having asliding and pivotal connection with the rocking frame 3 3 which derivesfrom the switch'- cam 21 upon the main-shaft its rocking movements ofone-half the frequency of the needle-bar reeiprocations Adjustablysecured upon a seat 66 upon risate? the underside of the bed-plate bymeans of the screws 67 passing through slots 68 therein, is the .foot 69o-f a bracket formed with a bearing boss70sin .which is journaled therotary loop-taker shaft 71 upon the upper end of which is xed ltheloop-taker '72 formed with the loop-seizing beak 73 coperating with theiixed needle 61 and having taker shaft 8.7 and to the plane of lateralmovement" of the jogging needle v5,4. The pins 82 are secured by meansof set-screws 83 within spaced bosses 84 of av jogging frame 85 formedwith an upwardly eXt'end-I ing bearing member .86 in which is journaledthe loop-takerv shaft 87 upon which is fixed the jogging loop-taker 88which isprovided `with the beak 89 adapted for coperation with thejogging needle 54 and having ournaled .therein the non-rotatingthread-case 90 formed -with the laterally vextending finger 91 and`containing the lower thread .bobbin 92. The jogging frame 85 is formedwith the divergently extending lateral arms 93 formed withthe'perfora-ted bosses 94 in which vis secured by means of theset-screws A95 theslide-pin 96 disposed parallel with-the fulcrum-pins82, and enteringv a-transverse aperture in the block 97 which has asecond aperture fitted tothe actuating eccentric 98,

as represented more particularly in Figs. 1

and 2. y

Journaled in the depending bearing members 99 'ofthe bed-plate is thehorizontally disposed intermediate shaft 10Q arranged in transverserelation both to the 'loop-taker' shafts and to the fulcrum .of-thejogging frame 85 and having fixed thereon by means of the set-screw 101the bevel-pinion 102 meshing with the similar pinion 103lsecured uponthe lower end 'of the loop-taker shaft 71, and having a secondbevel-pinion l104 secured thereon by means of thev set-screw 105, andmeshing with La similar pinion 106 which is fixed upon the lower end ofthe loop-taker shaft'87. The fulcrum-pins- 82 are so disposed relativeto the pinions 104 and 106 that their aXispasses approximately throughthe intermeshing point of, such pinions so Aas to permit the slighttilting movement-of the frame 85 without materi-4 ally\aifecting theintermeshing relation of such pinions.l As represented in the drawings,the part of the frame 85 intermediate" the bosses 84, is cut out toafford clearance for the pinions 104 and 106.

` Thelinterinediate shaft has fiXed its rearward end by `means of" theset-screw 107 the hub 108 of the pinion 109 which meshes with thegear-wheel 110 havingits hub 111 secured byaneans of the set-screw 112upon the] lower shaft- 113 which is formed with quartering cranks .114connected bymeans of the pitmen 115 with the similarly arranged craks116 formed i-n the main or needle-driving shaft 17. As the .plnion .109is one-half the size of the gearwheel110, and the bevel-pinions 102,103,

104 'and 106 are uniform in size, it will be observed thatv theloop-takers 72 and 88 derive from the main-shaft two complete rotationsfor each reciprocation lof the needlebar.

vThe eccentric 98 is secured u'pon the hub '117 of a gear-wheel118loosely. mounted upon the intermediate shaft 100 and held againstlateral displacement thereon by means of the thrust-collar 119. Meshingwith the gear-wheel 118 is the pinion 120' whose hub 12.1 isadjustaldliy secured upon the` shaft 113 by means of the set-screw 122vand serves to `impart to the eccentric,`

through the gear-wheel. 118, rotations at one-half. the speed oftheshaft 113 and the connected needle-bar actuating shaft 17 Byv themeans described, the loop-takers 72 and 88 are caused to perform uniformcircular movementsI in which their excursions from an initial position',such as loopseizing position,` are'performed with greaterfrequency thanthe lateral jogging move- 'ments of the needle 54 and the loop-.takersupport 86.` I'lie'relation between the rotat` lCO ing meansV and the.jogging means'of the lat.- A

erally movable loop-taker 88 is such that the coperative relation of theloop-taker with its respective needle is uniform regardless of theirlateral positions.

It is evident that, not only must the loop:

taker bea-k cross' the needle-path just after the needle 'begins to risefor presentation .of

its thread-loop thereto, but that'the 4beak must move close to theneedle, whatever the latterslateral position,' at the loopseizinginstant.- Compensation for variations in .the lateral position of theneedle at such timemay be eected in either of two ways. rllhe loop-taker may follow 1 the' needle-jogging movements in the amplitude lofits lateral movement, in the customary manner, or a fixed period ofuniform lateral movement thereof may be advanced or delayed in timing sothat any excess of such `uniform `maximum lateral movement may occurafter the loop-seizing instant, the further and superfiuous lateralmovement of the -looptaker being immaterial as regards the cooperationof the stitch-forming elements. In other words, so long as theloop-taker has the correct lateral position relatively to the needle 'atthe loop-seizing instant, it is Wholly immaterial Whether thereafter thevloop-taker continue a lateral movement thenvin progress'or immediatelyperform a retrograde movement. The second of the' alternativesabovedescribed is. that adopted in the present embodiment of this invention.

lThe compensative lateral loop-taker movements are ei'ected in thepresent instance by resetting the pinion 120 upon its shaft bytemporarily loosening the set-screw 122` so. as to advance or retractthe loop-taker jogging, cam 98 circularly for bringing the loop-takerlaterally into operative relation with the needle When inloop-presenting position, lbut prematurely as regards its (theloop-takers) further range of uniform lateral movement. It is, ofcourse, unnecesj sary that the loop-taker should be laterallystationary, or at the point of reversal of its lateral" movements,duringl the loop-seizing action, so long as -its continued lateral lmovement be not of such character as to cause injurious collision withthe then rapidly rising needle. nism, the loop-taker has so littlebodily lateral'movement andl theneedle performs its rising movement sorapidly relatively there-4 to, that thereis no interference betweenthesestitch-forming elements.

. lever 25 27, any changes in the amplitude of lateral movements of theneedle insuring the.` descent of thevneedle alternately in eX- tremepositions equi-distant from such neutral position, in the presentmachine. is thus evident that adjustments of the looptaker-joggingmechanism to correspond with a .given amplitude of lateral movements ofthe needle will cause the loop-taker to cooperate with the needleexactly -the same in each loop-presenting position thereof.

The bearing member 86 of the. jogging loop-taker sustaining frame. isAprovided with a lateralyseat beneath the loop-taker upon `Whichnissecured by means of'the fas-` tening screw 123 the. foot 124C of aholding arm 125 extendingxupwardly land terminating in a ,member 125"formed in' its-lower 4 faclegwith'fthe notch .126 to lreceive thelaterally? extending finger-91* of the thread-case 90',A` andad'apted tovrestrainthe latter against rotary movement 'with .the loop-taker. 88..

The-arm 125 is formed With a lateral lug 127 having a socket in which issecured by means of the'set-screw 128 the shank of thethread-controlling finger 129 which is disposed substantially-upon ja,level with the` top of the loop-taker and intermediate the latter andthe path of reciprocation of the jogging needle 54. In order toprevent't e escape of the thread which it controls, tie finger 129 has alateral extension 130 at its extremity.

Secured upon the bed-plate is ther throatplate 131, constituting theWork-support Which is formed with the usualfeed-dog apertures 13 2 andthe needle-apertures 133 and' 134, the former being inthe form of atransverseslot to accommodate the jogging needle 5-1. Secured upon aseat intermediatethe feed-dog apertures by means of screws 135 is theneedle-'guard 136 formed with the usual oppositely. facing grooves137 toreceive the respective needles and to -insureA the throWing\,out oftheir thread-loops Wholly upon the sides loccupied by their respectiveloop-takers. The throat-plate is shown provided at one edge withdependmg spaced holding lugs 138 embracing the lateral finger 74: of thethread-case 74 to restrain it against rotation With its sustainingloop-taker 72.

The machineis shown providedwith the presser-bar 139 to which is securedthe shank of the presser-foot 140"opp`osed to the feed-dog 141' havingfeed points extending through' the throat-plate apertures 132 andsustained by the feed-bar 142 connected With and deriving operativefeeding movements from'the rock-shaft 143 Which rel ceivesits rockingmovements from the actuating eccentric 144 through suitable connections,the feed-bar deriving its rising andA falling movements from therock-shaft 145 Which receives its rocking movements from the feed-lifteccentric 1116.

. In the use of the machine, the loop-taker 72 cooperates With the fixedneedle 61 i`n the production of a straight seam and the loop-taker 86follows the lateral movements of the jogging needle 54 in theproduction, of a zigzag seam. In .the ordinaryadjustment of' the parts,the overlapped -marginal portions of the sole a and'upper of the tabiare stitched together by the line of 4straightavvay stitching c and theraw edges arebound by 'means of the line of zigzag stitching 'd in whichthe in-throW punc- -tures of the joggingneedle 541` are in substantialalinement vwith thest'raight row of vpunctures vof the Xed needle 61, asrepre-` sented in Fig. 14. When the machine is used in connection withloose-textured fabrics requiring a'm'ore. secure anchorage forVthe`binding overseam d, the position of the in-throwv punctures` of thejogging needle maybe arranged beyond the straight-away seam `c byslightlyl shifting the jogging cam 21 upon the main-shaft 17 oradjusting the arm '40v uponthe crank-rod 43; or sidepointed needles, asrepresented in Fig. 13, may be employed with their points set opineens?positely, and that of the jogging needle arranged in the direction ofthe in-throw, so

that the threads of the-straightavvay and over-edge seams will becrossed, as represented in Fig. l5. l

To provide for more effectively covering the i'aiv edges of the Work,the slide-block.

50 may he constructed to hold two needles arraiigedin the line of feed.As represented iii Fig. 12, the extension 51 of the block has a socket147 against one Wall', of

which are clamped the shanks of tWo needles` 5l and'l by means ofthechanneled'block 148 Awith convergently inclined Walls engaging theneedle-Shanks and pressed, against the same by means of the clamp-screw53.

v lVith'the needlecarrying slide-block 50 thus constructed and equipped,a double-zigzag overseam may be produced with the se'ains CZ and rloverlapped upon the upper face of the Work and which may be anchored or,a circularly movingdoop-taker. cooperating not, as may bedesired, inthe straight-away seam 2, as represeiitedin Fig. 16.

lF rom the'foregoing description, it will be evident that lthe presentimprovement` is' not limited to the specific embodiment here-l in Ashown-and described, but may be lvery `materially modified in theconstruction and arrangement of its parts Within the .scope of theinvention. j
